Definitions

  • the invention relates to an air supply device consisting of at least one air passage which can be connected to an air duct via an air connection box and with which air can optionally be introduced more or less vertically or horizontally into a room to be ventilated.
  • Such air supply devices are generally known and require air connection boxes to be interposed between the air duct and the air passages if a direct connection of the air passages to the air duct is not possible due to lack of space or is undesirable for optical reasons.
  • the invention has for its object to provide an air supply device of the type described above, which makes it possible to significantly reduce the respective air passage and thus also the air connection box, without thereby causing a reduction in the volume flow that can be introduced into the space to be ventilated with each supply device.
  • an air supply device of the type specified in the preamble of claim 1 is assumed and proposed according to the invention to provide areas with perforations in the floor and / or wall parts of the air connection box, which perforations surround the outlet opening of the air passage.
  • connection box Since the connection box is designed to be tight, the total volume flow for the air supply device can be divided so that only a partial volume flow is applied to the air outlet and a remaining partial volume flow is introduced directly into the room through the perforations in the air connection box. As a result, the correspondingly less air passage can be made small in size. This reduces the costs for the air passage and thus also the costs for the overall construction of the air supply device, especially since the air connection box can also be dimensioned correspondingly smaller, which also has a cost-saving effect.
  • a perforated base part of the air connection box and the outlet opening of the air passage are arranged essentially in the same plane.
  • the flow direction of the partial volume flow introduced into the room via the perforations in the air connection box can be influenced by the respectively selected flow direction of the partial volume flow introduced into the room via the air outlet.
  • the perforations in the circular disk-shaped base part of the air connection box are distributed over a radially outer area and the perforations in the cylindrical wall part of the air connection box are distributed over a lower area connected to the bottom part of the air connection box.
  • a further embodiment of the invention provides that above the perforations in the air connection box there is at least one partition which also divides the interior of the air connection box and is provided with perforations.
  • Such a perforated partition preferably consists of an annular disk extending over the horizontal cross section of the air connection box.
  • a perforated partition consists of a cylinder which is connected with a lower edge to an edge of an inlet opening of the air outlet and with an upper edge to a ceiling side of the air connection box.
  • the dividing wall formed from a cylinder provided with perforations in particular smoothes the flow of air through the air outlet and improves its acoustics.
  • the air supply device contains a conventional air passage, generally designated 1, which is designed as a swirl passage and is equipped with an actuator 2 for beam deflection. Swirl blades 3 are arranged concentrically around this. With the help of the actuator 2, a jet guide device 4 arranged in the outlet area of the air passage 1 and acting as a rectifier can be adjusted in height.
  • the partial volume flow directed through the annular space of the air passage 1 flows vertically from top to bottom (FIG. 1) or essentially horizontally (FIG. 2) into a room to be ventilated.
  • the air passage 1 is arranged within an air connection box, designated overall by 5. This consists in particular of an annular disc which forms a bottom part 6, an outer cylinder which forms a wall part 7, an inner cylinder which connects to a jacket of the air passage 1, a circular disc which forms a ceiling part 9, and a connecting piece arranged on the side 10, which can be connected to an air duct, not shown.
  • Perforations 11 are provided in the bottom part 6 and in the adjoining lower area of the wall part 7, through which perforations a partial volume flow enters the space to be ventilated.
  • a partition 12 formed from an annular disc, which is provided with perforations 13 and extends over the horizontal cross section of the air connection box 5.
  • the interior of the air connection box 5 is divided by a further partition wall 14 formed from a cylinder, in which perforations 15 are also provided.
  • the partition 14 is connected with its lower edge to the jacket 8 and with its upper edge to the ceiling part 9 of the air connection box 5.
